How are windows framed?
Home » Homebuilding » Framing » How are windows framed?Windows typically have a single or double sill across the base, made up of two by fours laid flat. Trimmer studs support each end of a header and cripple studs fill in the areas above and below the openings. Cripple studs are placed on the 16- or 24-inch stud layouts.
Wherever windows, doors or other openings occur along a wall, the regular studs are eliminated. Instead, a small beam, called a header, spans across the top of the opening, bridging the gap.
A double top plate-two 2" x 4"s or 2" by 6"s laid flat-caps the top of the studs, locking studs in position, giving the wall rigidity and support and providing a backing for nailing-on wall covering materials.
At the wall's base, studs are nailed to a 2" by 4" or 2" by 6" sole plate to lock them to the floor.
The wall frame generally consists of 2" by 4" or 2" by 6" wall studs placed vertically every 16 or 24 inches, from center to center. Extra studs provide nailing area and sturdy support wherever walls intersect, such as at corners.
